"EPA wants to allow perchlorate in drinking water to reach concentrations 10 times higher than standards set by states and three times higher than the agency's own reference level.
In a proposal released yesterday for regulating the rocket fuel ingredient that has been linked to thyroid problems, EPA suggests setting a maximum contaminant level and health-based maximum contaminant level goal of 56 parts per billion.
That's orders of magnitude higher than standards set by the two states that have regulated perchlorate.
Massachusetts' standard is 2 ppb, while California is considering lowering its standard of 6 ppb to 1 ppb."
